  2. BATP but not sugar
  3. Cboth ATP and sugar
  4. Dneither ATP nor sugar.

Correct answer

D. neither ATP nor sugar.

Step-by-step solution

Photorespiration is the light dependent process of oxygenation of ribulose biphosphate (RuBP) and release of carbon dioxide by the photosynthetic organs of a plant. Normally photosynthetic organs do the reverse in the light, i.e., uptake of CO ₂ and release of O ₂ . At high temperature, RuBP carboxylase functions as oxygenase and instead of fixing carbon dioxide ( C ₃ cycle), oxidises ribulose 1,5 -biphosphate to produce a 3-carbon phosphoglyceric acid and a 2-carbon phosphoglycolate. Photorespiration does not prod
